[fre] L'objet de cet article est de préciser certains points des relations théoriques qui existent entre les indices de concentration et les mesures du pouvoir de monopole. Après avoir présenté une généralisation de l'indice d'Herfindahl, l'auteur propose des indices adaptés au cas de l'entreprise pilote. Il est enfin montré que le passage du pouvoir de monopole au taux de marge bénéficiaire au niveau de l'industrie peut présenter certaines difficultés lorsque la concentration est mesurée par le taux de concentration. [eng] Concentration indexes, monopole power and conjectural variations : some extensions The purpose of this paper is to make clearer some aspects of the theoretical relationships that exist between the concentration indices and the measures of the monopoly power. First presenting a generalisation of Herfindahl index, the author then puts forward some indices which fit in with the cas of the leading firm. It is finally demonstrated that some difficulties may arise as we pass from the monopoly power to the ratio of profit to revenue at industry level, when the concentration is measured by the concentration ratio
